Caustic (optics) - Wikipedia
网页The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. [ 2 ] In some cases caustics can be seen as patches of light or their bright edges, shapes which often have cusp singularities.
What Are Caustics and How to Render Them the Right Way
网页2019年11月8日 · What Are Caustics and How to Render Them the Right Way. Caustics are everywhere in the real world but rarely seen in renders. Learn why they’ve been ignored — and how you can now render them effortlessly in Corona. First, let’s refresh our knowledge of what a caustic is.
Caustics: What They are and How to Render Them - GarageFarm
网页In simple terms, caustics are the light patterns created when light rays are focused through reflection or refraction from a curved surface. Imagine the bright patches of light you see on the floor when sunlight passes through a glass of water—that’s a caustic effect.
Caustic Definition & Meaning - Merriam-Webster
网页noun. 1. : a caustic agent: such as. a. : a substance that burns or destroys organic tissue by chemical action. b. : a strong corrosive alkali (such as sodium hydroxide) 2. : the envelope of rays emanating from a point and reflected or refracted by a curved surface.

网页2021年8月18日 · Caustics are the bright patches of light we see when illuminating a transparent object. All the photons that don't pass directly through the object are what form the object's shadow. All those photons still have to go somewhere; they contribute to the caustic pattern.
Caustic (mathematics) - Wikipedia
网页In differential geometry, a caustic is the envelope of rays either reflected or refracted by a manifold. It is related to the concept of caustics in geometric optics. The ray's source may be a point (called the radiant) or parallel rays from a point at infinity, in which case a direction vector of the rays must be specified.
Caustic - Encyclopedia of Mathematics
网页2014年12月13日 · Caustic. The envelope of rays reflected or refracted by a given curve. The caustic of reflected rays is called a catacaustic, that of refracted rays — a diacaustic. For example, the catacaustic of a parallel beam of rays reflected from a semi-circle is part of an epicycloid (see Fig. a); the diacaustic of a pencil of rays emanating from a ...
CAUSTICS - UC Santa Barbara
网页Caustics are complex patterns of shimmering light that can be seen on surfaces in presesnce of reflective or refractive objects such as those formed on the floor of a swimming pool in sunlight. Caustics occur when light rays from a source, such as the sun, get refracted, or reflected, and converge at a single point on a non-shiny surface, which ...

网页2002年10月7日 · Caustics are formed by light that is reflected or transmitted by a number of specular surfaces before interacting with a diffuse surface. Examples of caustics are the light patterns on the bottom of a swimming pool and light focused onto a table through a glass of cognac.

网页2020年9月27日 · Especially when forming with light, caustics are popular phenomena in everyday life. They occur when sunlight is reflected or refracted at smoothly curved surfaces and as a result is focused on high-intensity lines. Download chapter PDF.
